But I think approximately everyone has at least one of those beliefs; it’s just not that obvious because many of these strange beliefs are idiosyncratic, and people often hide them from each other and sometimes even from themselves (by avoiding thinking about that belief, or by not reflecting on how crazy the belief would seem to others).

For one person, the weird belief may be their lucky coin (see this lovely essay that I learned about from @mariellevolz after writing a first draft of this essay).

For another person, it may be an unsupported belief that they are unlovable.

For a third person, it might be an attachment to a certain diet that they’re convinced would solve all sorts of problems if everyone would just go on it (like they did).

Or it could be a strange belief they learned from their childhood religion, which everyone except adherents of their exact denomination of their religion sees as ridiculous.

And so on.

Because I think just about everyone has strange false beliefs like this, I try not to judge people too much based on the fact that they have a “weird” belief that I think is way out of alignment with reality. Of course, even if I’m right, that doesn’t mean everyone is an equally “bad” thinker.

Some people think, “That person believes X, what an idiot,” and write the person off. I aspire not to do that based on one crazy belief but rather to look at a person’s beliefs and how they arrive at their beliefs more holistically.

Being an effective thinker is better measured by how we do, on average, on the important things (weighted by their importance) rather than the worst thinking we do on any single topic.

I also believe that with time and consistent effort, we all can get better at thinking clearly and that it’s a worthwhile investment for most people.

But even with hard work, we’re unlikely to get to zero weird false beliefs.

Gaslighting, where someone causes another person to doubt their sanity or senses, can cause psychological damage.

There’s an opposite thing, though, that can also be damaging. As far as I know, it has no name. I call it “lightgassing” (or “light gassing”). Here, I explain how lightgassing works.

Lightgassing is when one person agrees with or validates another person’s false beliefs or misconceptions in order to be supportive. 

Unlike gaslighting, a tactic of jerks and abusers, lightgassing is an (unintentionally harmful) tactic of friends and supporters.

Here are common examples I’ve seen that are sometimes, but obviously not always, lightgassing:

• “Since they did X, they don’t deserve to be with you.”

• “It was reasonable for you to do Y because they made you feel bad.”

• “You did nothing wrong. It was 100% their fault.”

Ideally, when you’re upset, friends should validate your feelings and help you feel heard and understood, but they should do so without agreeing with statements they themselves know to be false.

We do a disservice to people when we encourage their false beliefs. Most people have a value of truth-telling (and knowing the truth), and by avoiding lightgassing, we stay truer to these values.

But how does one listen with openness and empathy to an upset friend and still validate *feelings*, without validating *false beliefs*? This can be a tricky maneuver, which I think is one reason people feel tempted to lightgas.

If you want to avoid lightgassing, the key is to validate those elements of a person’s *beliefs* that you know to be true while empathizing with them and validating that their *emotions* are understandable and okay to feel. But the key is to do this without reinforcing beliefs in false things.

I think it’s usually not helpful to challenge what another person believes is true right in the heat of emotion when that person is sad or upset. So avoiding lightgassing will often initially involve simply not validating/agreeing with what you believe is false. Later, when the person is feeling better, if they ask for your opinion on the facts (or you feel it’s important for them to hear your opinion), you can tell them what you believe to be true at that point.

A caveat that I think is worth mentioning is that sometimes, the only thing we know about a situation is what our upset friend or loved one has told us. In such cases, I think we should start with the assumption that what they have described is an accurate representation of what they experienced (unless any reason to doubt it emerges).

Lightgassing (or light gassing) typically happens in ordinary situations where someone feels hurt or upset. But it can also happen in more extreme situations, such as when you’re trying to help someone who is feeling upset due to severe delusions caused by psychosis. 

In the case of someone with psychosis, the path of least resistance is to lightgas them by agreeing with their delusions, but this is not in their own interest. On the other hand, if you invalidate their emotions, you will likely make them more upset and may lose their trust. The tightrope to walk is to help them feel cared about, listened to, empathized with, and understood, without saying that their delusions are reality. In other words, to avoid lightgassing them while also not causing them to feel gaslit.

Does lightgassing really deserve its own term? Why not just call it “enabling”? Well, lightgassing can be a type of enabling, similar to how gaslighting is typically a form of manipulation. But lightgassing is much more specific than enabling, and enabling can include lots of things that are not lightgassing (e.g., buying an alcoholic some alcohol is a form of enabling but not lightgassing). Having a more specific term (lightgassing) makes it easier to spot and communicate about this specific pattern of behavior.
